Not that Granite needs any backup, but I can say I've experienced many paranormal things myself. I don't doubt what he is saying at all. I've seen orbs I couldn't debunk, I've been "scratched" by an incorporeal entity or perhaps better to say singed, and I've had a medium give me detailed directions and landmarks to find my way through a forest to find three objects that there is no way she could have known were there since she has never been to the US. and yes I've met the woman personally in Canada and I know she has never been to the US, especially where I live.
I can't speak for Granite but I think he might agree when I say I don't need to prove it to anyone. I know what I experienced and quite frankly I don't expect anyone who hasn't experienced it to believe me. I will however ask that people actually go do a few months or years of research in the field to be able to validate their skepticism instead of playing armchair quarterback on an internet forum where there is no chance him or I could convince you of anything.
